MACHINE FOR MAKING GROOVED STRIPS.

Application filed December 13, 1924.

This invention relates to machines for making grooved strips such as will serve as a lock for oppositely curved and flanged edges of a metal container. The invention is fully described in the following specification and shown in the accompanying drawings, in which:

Figure 1 is a partial side elevation of the machine embodying the invention;

Fig. 2 is continuation of the same;

Fig. 3 is an enlarged sectional view on the line 3 of Fig. 1, showing the first set of rotary shearing rollers;

Fig. 4 is a front elevation of a strip of metal having been acted upon by feed rollers; v

Fig. 5 is a transverse the line 55 of Fig. 3;

showing a pair of feed rolls;

Fig. 7 is a similar section on the line 7 of Fig. 1 showing the first pair of forming rolls;

Fig. 10 is a section of the strip after having passed the forming rolls of Fig. 9;

Fig. 11 is a section on the line 11 of Fig.

i 1, showing the third set of forming rolls;

Fig. 12 is a transverse section of the strip as it emerges from the forming rolls;

Fig. 13 is a vertical section on the line 13 of Fig. 1;

Fig. 14 is a transverse section of the strip as it emerges from the forming rolls of Fig. 13;

Figs. 18, 19, 20, 21 and 22 are similar views taken on the lines 18, 19, 20, 21 and 22 respectively; v

Fig. 23 is a transverse view of the grooved strip as applied to a container; and

Fig. 24 is a vertical longitudinal section through the next pair of rolls at the right hand end of Fig. 2.

Serial No. 755,703.

The embodiment illustrated comprises a machine having a main frame 25 and is supported on suitable legs 26 and which has a machined upper surface 27 upon which is adjustably secured a series of carriages 28 which are held between longitudinally beveled strips 29 and secured by means of bolts 30.

Each of these carriages has two vertical cars in which are disposed vertical slots 31 which are adapted to receive lower journal boxes 32 and upper journal boxes 33 in which are journaled shafts 34 and 35 which carry meshing gears 36 and 37. The shaft 36 has a worm gear secured thereto which meshes with a worm wheel 39 on the shaft 40.

The shaft 40 extends throughout the length of the machine and is journaled in suitable bearings 41 and driven by means of a pulley 42 from a source of power, not shown. Several shearing and forming rolls which will hereafter be described are all mounted in substantially the same way and all are driven from the longitudinal power shaft 40. The springs 43 are placed between the journals 32 and 33, the latter being adjustable by means of a screw 44 and lock-nut 45.

Rotary shearing rolls 46 and 47 are keyed upon the shafts 34 and 35, the roller 47 having side cutting jaws 48 which mesh with openings 49 whereby recesses 50 are cut at regular intervals from the sides of the strip A as shown in Fig. 4. I

After passing the first pairof shearing rollers the strip A passes between feed rolls 51 and 52 which are mounted and driven similarly to those previously described. While only this one pair of strictly feed rolls are shown, it will be understood that others may be inserted where necessary to propel the strip through the machine. One of these rolls has flanges 53 to serve as a guide for the strip A. Between the several rolls is a table 54 which extends between the rolls as shown in Figs. 1, 2, 5 and 24. This table serves to maintain the strip at the proper level while passing through the machine.

Fig. 7 shows the first pair of forming rolls 55 and 56 and Fig. 8 shows the strip A as its edges are curved upwardly by these rolls In Fig. 9 the roll 57 is flanged, while the roll 58 runs between the flanges so as to turn the side flanges of the strip A vertically upward as t emerge t refr m a h w n ill) .central flange.

- whi'c Fig. 10. In Fig. 11, the upper forming roll consists of a central flange 59, conical flanges 60 passing at each side thereof and spaced therefrom, the cones. converging toward the As the strip A passes strip will force it inward and curve it as .shown in Fig. 12. A simi ar roll 61 is next in succession and closes the stri A still further as shown in Fig. 14. ollowing these the rollers 62, 63 substantially closes the strip leaving it in the form A as shown in Fig. 16. In practically all these rollers sufiicient pressure can be applied to close the rollers to feed the strip along without the necessity of intervening feed rollers.

Figs. 17, 18 and 19 show the edges of feed rollers 64, 65-66, 67 and 68, 69 which bend up the sides of the strip at A and A and fold it over at'A. This foldin action is ig. in

central vertical flanges 72 of the strip A are passed between stationary guides 73 have bevel guideways 74 against which the flanges 72 are ressed by means of the conical rollers 75. nFig. 22 the strip is given its final form by bending down these portions 72 over the thin flat bar 76 by means of a roller 77. 7

Thus a completed grooved stri A is formed which is double throug out the greater portion of its length and has an opening adapted to receive endwise the oppositely flanged edges 78 of the container 79.

By this arrangement a much stronger and ri id connection is obtained and one which so joint. To further decrease any further pos sible leakage and render the joint still tighter, the connection may be pressed or hammered down as described.

The strip having been formed as previously described, thenpasses the shearing rollers 80'and 81 which separate the stri s at the recesses on the'dotted lines as in icated in Fig. 4. v v
